it helps some times I used D3 Here is an example of scatter chart with images: http://plnkr.co/edit/A60Pv8I7tqSVGKU64bgr?p=preview
src code:
// Code goes here
var h = 500;
var w = 750;
var padding = 50;
//set your images and data here
var monthlySales = [{
  'stock': 'GOOG',
  'count': 500,
  'img': "https://encrypted-tbn3.gstatic.com/images?q=tbn:ANd9GcTccGK4ZWQcI3WB--hytI1DFaeZ8ii-6euDWrm-baUtAxR7w9OrWg"
}, {
  'stock': 'MSFT',
  'count': 250,
  'img': "http://tr1.cbsistatic.com/fly/171-fly/bundles/techrepubliccore/images/icons/standard/icon-user-default.png"

}, {
  'stock': 'FB',
  'count': 50,
  'img': "https://cdn1.iconfinder.com/data/icons/industry-2/96/Mine-512.png"

}, {
  'stock': 'AAPL',
  'count': 100,
  'img': "https://cdn1.iconfinder.com/data/icons/industry-2/96/Mine-512.png"

}, {
  'stock': 'EBAY',
  'count': 5,
  'img': "https://cdn1.iconfinder.com/data/icons/industry-2/96/Mine-512.png"

}, {
  'stock': 'BABA',
  'count': 37,
  'img': "https://cdn1.iconfinder.com/data/icons/industry-2/96/Mine-512.png"
}];


var xScale = d3.scale.linear().domain([65, 450]).range([0, w]).nice();
var yScale = d3.scale.linear().domain([0, d3.max(monthlySales, function(d) {
  return d.count;
})]).range([h, 0 + padding]).nice();
var radiusScale = d3.scale.linear().domain([0, d3.max(monthlySales, function(d) {
  return d.count;
})]).range([10, 100]).nice();
var opacityScale = d3.scale.linear().domain([0, d3.max(monthlySales, function(d) {
  return d.count;
})]).range([1, 0.1]).nice();

function ordinalValue(item) {
  var strLen = item.length;
  var total = 0;
  for (var i = 0; i < strLen; i++) {
    total += item.charCodeAt(i);
  }
  console.log(total);
  return total;
}


var svg = d3.select('body').append('svg').attr({
  width: w,
  height: h,
  style: "outline: thin solid blue"
});

var dots = svg.selectAll('g')
  .data(monthlySales)
  .enter()
  .append("g");

  dots.append('circle')
  .attr({
    cx: function(d) {
      var ordValue = ordinalValue(d.stock);
      return xScale(ordValue);
    },
    cy: function(d) {
      return yScale(d.count);
    },
    r: function(d) {
      return radiusScale(d.count);
    },
    fill: function(d) {
      return '#' + Math.random().toString(16).substr(-6);
    }
  }).style({
    "fill-opacity": function(d) {
      return opacityScale(d.count);
    },
    "stroke": function(d) {
      return '#' + Math.random().toString(16).substr(-6);
    }
  });
//adding an image to the group
dots.append("svg:image")
    .attr("xlink:href",function(d) {return d.img})
    .attr("height", "20")
    .attr("width", "20")
    .attr({
    x: function(d) {
      var ordValue = ordinalValue(d.stock);
      return xScale(ordValue)-10;
    },
    y: function(d) {
      return yScale(d.count)-10;
    },
  });

Draw wordcloud for each point in scatterplot

may help you . You have a couple of problems here.
First, your data has strings for the words. I changed that for an array of objects:
var data = [[5,3,[{'text':'word1',size:4},{'text':'word2','size':1}]], 
        [3,5,[{'text':'word3',size:5},{'text':'word4','size':4}]],
        [1,4,[{'text':'word1',size:3},{'text':'word2','size':5},{'text':'word3','size':2}]],
        [2,3,[{'text':'word2',size:1},{'text':'word3','size':5}]]];
div.append("svg")
    .attr("width", 300)
    .attr("height", 300)
    .attr("class", "wordcloud")
    .append("g")
var circle = g.selectAll("scatter-dots")
    .data(data)
    .enter()
    .append("svg:circle");
circle.on('mouseover', function(d){
    div.style("display", "block")
    d3.select("krog").style("fill", "orange");
    generate(d[2]);//here, d[2] is the third element in the data array
});
function generate(thisWords){
    d3.layout.cloud().size([800, 300])
    .words(thisWords)
    .rotate(0)
    .fontSize(function(d) { return d.size; })
    .on("end", draw)
    .start();
}

Draw 3d contours on scatterplot


Tag : r , By : Lauren Kirschner

To fix the issue you can do I think your data may not have a value of z for each possible combination of x and y values; you could not have a matrix that is "x" rows and "y columns and have a value of z at each index, you would have gaps. You may still be able to get what you want with geom_density_2d(), however. Given your example data above:
x<-c(0.15395671, 0.18148413, 0.07870902, 0.1351497, 0.03504008, 0.0216168)
y<-c(0.1548728, 0.1554308, 0.1538021, 0.1134729, 0.1053258, 0.1140364)
z<-c(-0.09622222, -0.1091111, -0.02911111, -0.1133333, 0.004222222, 0)

xyz <- data.frame(x,y,z)

ggplot(xyz, aes(x, y, z = z) ) + geom_density_2d()

Why do I get a KeyError when attempting to draw a scatterplot?

may help you . The answer is simple: your colour mapping is wrongly defined.
iris_dataframe["group"] contains ['setosa', 'versicolor', 'virginica'].
colors_palete = {'setosa': "red", 'versicolor': "yellow", 'virginica': "blue"}
